wait till you get into the higher difficulties...youll get so owned so fast youll wonder what hit you. This game is very gear dependant on the higher levels. You will curse the demon archers in act 4
As for a good templar build, i usually go with the trance of convelesnce for the healing and dmg reduction. Its generally the best aura for anyone. I would only put one point into adrenaline just so you can max out defensive reaction (i think thats what its called) for max dmg. The healing even at max level is paltry and not worth 12 points. Rally can be useful in parties, but why put points into something you can spend gold on and pick up? (potions). Id rather put points into quick recovery (a MUST) TQ shields suck without this skill cuz they have a 3 second cooldown before they can block again. This skill makes shields godly.
As for the rest...since your using PS, you dont need batter or charge. Max out armor handling ASAP for armor absorption, and max out pulverize ASAP. with a high lvl shield you will OWN groups. And make sure you up colossus form when you can...great for bosses. The aura that the defender has (forget the name) is really good too. Just put a point into the bottom node then max out the skill that ups your chance to block and get iron will up as high as you can. You will not believe how important stun resistance is.
so basically the only skills to max in defense is defensive reaction, armor handling, quick recovery, and pulverize. And colossal form eventually.
As for dream, dont even bother with psonic touch as youll have pulverize. Get rid of distortion wave, thats for casters. Max phantom and its other node ASAP. And max out distortion wave and its other node ASAP. one point in the pet with one point in hypnotic gaze is great to keep guys off of you. max out the trance of convalescence ASAP. Lucid dream is a must as well as the one that ups offensive and defensive ability. And temporal flux is a must too. Youll be stretched thin with skill points so try to get the skills that are always active maxed first, like armor handling and the trance.
Im a self proclaimed expert in TQ as Fat Kid can tell you...ive dumped more than 500 hrs prolly into this game and have done every build you can think of....if you have a question, dont be afraid to ask me. Good luck and have fun...it really is a great game.
EDIT - Also, heres what you should be going for as far as resistances go - (in order of importance)
1. Piercing
2. Fire
3. Poison
4. Lightning
5. Cold
I can not emphasize enough how important piercing resistance is. Arrows will be the bane of your existence on higher difficulties because it goes right through your armor. With max pierce resist, youll have a fighting chance. Fire is second only because its the most seen element in the game. Poison can be a real bitch too but its not seen that often. Lightning and cold you really dont have to worry about.
